Solar Energy is becoming increasingly important since theprices of gasoline, electricity, and other forms of energy are risingquickly. Solar Energy provides an alternative source of energy which isboth environmentally friendly and highly efficient.
This quiz will test and let you see for yourself just how aware you are of solar technology and its advantages.
Questions and Answers
- 1.
Solar thermal technologies can be used for water heating, space heating, space cooling and process heat generation.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Solar thermal technologies utilize the energy from the sun to heat water, provide space heating, cool spaces, and generate process heat. This is achieved through the use of solar collectors that absorb the sun's radiation and convert it into heat. The heat can then be used for various purposes such as heating water for domestic use, heating buildings, cooling spaces through absorption chillers, and providing heat for industrial processes. Therefore, the statement that solar thermal technologies can be used for water heating, space heating, space cooling, and process heat generation is true.Rate this question:

MIT's Solar House #1, built in 1939, used seasonal thermal storage for year-round heating.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
MIT's Solar House #1, built in 1939, used seasonal thermal storage for year-round heating. This means that the house was designed to store thermal energy during the summer months and use it for heating during the winter months. This technology allowed the house to maintain a comfortable temperature throughout the year, making the statement true.Rate this question:

What can be used to make saline or brackish water potable? The first recorded instance of this was by 16th century Arab alchemists. Individual still designs include single-slope, double-slope (or greenhouse type), vertical, conical, inverted absorber, multi-wick, and multiple effect. These stills can operate in passive, active, or hybrid modes.
- A.
Solar smelting
- B.
Solar distillation
- C.
Solar treatment
- D.
Solar heating
Correct Answer
B. Solar distillationExplanation
Solar distillation can be used to make saline or brackish water potable. This process involves using the heat from the sun to evaporate the water, leaving behind the salts and impurities. The vapor then condenses and is collected as purified water. This method has been utilized since the 16th century by Arab alchemists and can be implemented using various still designs such as single-slope, double-slope, vertical, conical, inverted absorber, multi-wick, and multiple effect. Solar distillation can operate in passive, active, or hybrid modes.Rate this question:

What is a concentrating technology employed by the Solar Kitchen in Auroville, India, where a stationary spherical reflector focuses light along a line perpendicular to the sphere's interior surface, and a computer control system moves the receiver to intersect this line. Steam is produced in the receiver at temperatures reaching 150 °C and then used for process heat in the kitchen.
- A.
Solar cusp
- B.
Solar spoon
- C.
Solar bowl
- D.
Solar cap
Correct Answer
C. Solar bowlExplanation
The Solar Kitchen in Auroville, India uses a concentrating technology called a "solar bowl." This technology involves a stationary spherical reflector that focuses sunlight along a line perpendicular to the interior surface of the sphere. A computer control system then moves the receiver to intersect this line. The receiver produces steam at temperatures up to 150 °C, which is used for process heat in the kitchen. Therefore, the correct answer is "Solar bowl."Rate this question:

Solar technology is capable of processing heat through which of the devices listed?
- A.
Solar receptor
- B.
Parabolic plate
- C.
Solar panel
- D.
Parabolic dish
Correct Answer
D. Parabolic dishExplanation
Solar technology is capable of processing heat through a parabolic dish. A parabolic dish is a device that uses mirrors to focus sunlight onto a single point, creating intense heat. This concentrated heat can then be used for various purposes such as generating electricity, heating water, or even cooking. The shape of the parabolic dish allows it to capture and concentrate sunlight effectively, making it an efficient device for processing heat using solar technology.Rate this question:

Sunlight can be converted into electricity using photovoltaics (PV), concentrating solar power (CSP)
- A.
Photovoltaics
- B.
Electrical power
- C.
Solar power
- D.
Electrons
Correct Answer(s)
A. Photovoltaics
C. Solar powerExplanation
Photovoltaics refers to the technology that converts sunlight into electricity using solar cells. Solar power, on the other hand, is the overall concept of harnessing the energy from the sun to generate electricity. Therefore, the correct answer suggests that photovoltaics is a specific technology within the broader category of solar power, which can convert sunlight into electricity.Rate this question:

A solar cell, or ______ cell (PV), is a device that converts light into direct current using the photoelectric effect.
Correct Answer(s)
photovoltaicExplanation
A solar cell, or photovoltaic cell (PV), is a device that converts light into direct current using the photoelectric effect. The term "photovoltaic" refers to the process of generating electricity from light, specifically by utilizing the properties of certain materials to create an electric current when exposed to photons. This term accurately describes the functioning of a solar cell, as it captures and converts sunlight into usable electrical energy.Rate this question:

A ______ consists of a linear parabolic reflector that concentrates light onto a receiver positioned along the reflector's focal line. The reflector is made to follow the Sun during the daylight hours by tracking along a single axis.
Correct Answer(s)
solar troughExplanation
A solar trough is a type of solar concentrator that uses a linear parabolic reflector to concentrate sunlight onto a receiver positioned along the reflector's focal line. The reflector is designed to track the movement of the sun throughout the day along a single axis. This design allows for the maximum amount of sunlight to be captured and converted into usable energy.Rate this question:
